title: Effective light bending and controlling in a chamber-channel waveguide system.
abstract: A novel chamber-channel system is proposed to achieve the bending of light at a 90 deg angle with relatively high transmission efficiencies. An ultrathin film is introduced into the chamber to couple more light into the system, which makes the chamber as a light absorber, while the channel serves as an output pathway to guide the light through the system. We show that the light propagation is significantly affected by the output position of the channels. By setting the output to specific positions, the device can be considered as a light switch, amplifier, or filter. This work holds great potential for controlling light in nanoscale photonic devices.
